Abstract:

In recent times, multi-storey buildings in urban cities are required to have column free space due to shortage of space, population and also for aesthetic and functional requirements. For this buildings are provided with floating columns at one or more storey. In the seismic regions the construction of these floating columns are highly disadvantageous. The earthquake forces that are developed at different floor levels in a building need to be carried down along the height to the ground by the shortest path. Deviation or discontinuity in this load transfer path results in poor performance of the building. The object of the present work is to study the behaviour of multistorey buildings having floating columns under seismic forces and observe the effect of shear wall in the same building. For this purpose three cases of multi-storey buildings are considered having 8 storey, 12 storey and 16 storey. All the three cases are considered having floating columns provided with and without shear wall, and also analysed for zone III, zone IV and zone V by using software Staad.Pro. Observation shows that the provision of floating columns is advantageous in increasing FSI of the building but is a risky factor and increases the vulnerability of the building. It is observed from the analysis that lateral displacement and storey drift of the building increases from lower to higher zones because the magnitude of intensity will be more for higher zones. By the use of shear wall these parametric values reduces in all the models. This analysis work provides a beneficial help on the parameters lateral displacement and storey drift in the multistorey buildings having floating columns with and without shear wall.
